/** \class SinclairToReciprocalCoherencyMatrixFunctor
* \brief Construct the reciprocal fully polarimetric coherency matrix
* with Sinclair matrix information.
*
* Output value are:
* - channel #0 : \f$ (S_{hh}+S_{vv}).(S_{hh}+S_{vv})^{*} \f$
* - channel #1 : \f$ (S_{hh}+S_{vv}).(S_{hh}-S_{vv})^{*} \f$
* - channel #2 : \f$ (S_{hh}+S_{vv}).(2*S_{hv})^{*} \f$
* - channel #3 : \f$ (S_{hh}-S_{vv}).(S_{hh}-S_{vv})^{*} \f$
* - channel #4 : \f$ (S_{hh}-S_{vv}).(2*S_{hv})^{*} \f$
* - channel #5 : \f$ (2*S_{hv}).(2*S_{hv})^{*} \f$
*
* This is a adaptation of the SinclairToCoherencyFunctor, where \f$ S_{hv}=S_{vh} \f$.
*
* The output pixel has 6 channels : the diagonal and the upper element of the reciprocal matrix.
* Element are stored from left to right, line by line.
